Citizen Surveys & Data Analysis
Officer Carol Ogrinc
Notes from CALEA Conference
Orlando, Florida
Survey should be agency specific
Objectives must be clear
Must be defined
Have to know what to expect to find
Ask questions in a way so everyone knows what you are asking
Ask appropriate questions
Fulfill CALEA Standards and mandates
A 20% response is considered good
Refine your plan to set priorities for the next three years
Mail Surveys
Most common
Cost effective. One person can design and administer
Sampling frame (victims & witnesses)
Can get list of names from Tax Appraisers office
Single-family homes
Duplexes apartments, businesses, mobile homes, etc.
Instead of asking their income, ask a proxy question;
What is the value of your home?
What kind of vehicle do you own/drive?
Telephone Surveys
Able to obtain large sample
Are great sources of data
Turn around time is limited
Can purchase telephone lists
Many people use cell phones

Drawback if you rely solely on a phone book, you will miss younger people
Web Survey
Will get a 5 15% response
Responses are quick
Based on a convenience sample
Drawback Must have access to a computer (may miss elderly group)
Sotfware available Microsoft Frontpage
Personal Surveys
Should have some type of "giveaway" in exchange for their time
Focus Groups
Can ask what important issues are in their neighborhood
What is important to them?
Traffic problems?
Purpose of Surveys
To measure agency performance
Measure officer performance
Solicit recommendations for improvement
Identify citizen concerns
It is important to listen to people. They feel as though they have input in police/community.
Understanding the Scientific Method
Your goal is to get meaningful data
Must include control variables demographic variables
**Demographic variables (important)
Gender, race, income and education Is sample reflective of the true population?
-3-
Is data able to be generalized?
Agency performance be careful how you ask question
Everyone must be able to answer a question with a category that pertains to them.
Mutually exclusive can only give one answer to a specific question
Try to avoid "check all that apply" Is difficult to analyze
Likert Scale make sure you have a "neutral" category in the middle
Good | | | | | Bad
quite slightly neither slightly quite
or
(almost never) 1 2 (sometimes) 3 4 5 (most of the time)
5 point Likert should give you a normal distribution (graph) scale
(3) no opinion/neutral
Make sure you collect a large enough sample representative of your population
Ideal sample size at least 384
